China's increasing control of core tech has been coupled with an economic deceleration because of the inefficency in auturky and trade substitution. Huge market and growth are not the same thing; there is no correlation between size and growth.
As for GPS and space station; what they show is that the US can stop China for years while it itself is developing and ultimately, do no harm to US industry
As for the example of home-grown gps. Money.
